Question

(a) 4x²y + 4xy – 12y

Answer 1

For factoring the answer is
4y(x2+x-3)
For finding the gcf it is
4y
For finding the derivative-d/dx the answer is
D/dx{xn} =nx n-1
8xy+4y
For finding the derivative -d/dy the answer is
D/dy {yn } =ny n-1
4x2 +4x-12
For simplify the answer is
4x2y+4xy-12y
The degree is 3

Answer 2

4y(x^2+x−3)
